427 engine mounts. engine location

[Danielg]

Good info
I believe the rear end does not, or is not supposed to have any pinion angle. Why is because it is fixed, it is very difficult to achieve any anti squat charicteristics with IRS. level is what is best. However.....as you suspension travels up or down it can change depending on your design, thats when it gets tricky. I now have George's rear suspension, and the rear end/control arms are parrallel, ie level to the frame.
The theory of pinion angle I think applies to a rear end that will twist on it's springs, so to speak. I made my original frame off this theory also, the engine is level to the frame, and the rear end.....BUT offset elevation to create driveshaft angle.

Okay, back to engine position, I have mine I think done, the existing mount will not work, still not sure what they go to. So I will use mine.
New question, my rearend back from George, cobra racing, is not the one I sent him, I guess mine did not work with all the brake stuff. So....the differential mount pad is not parallel to the frame or control arms, does everyone modify the pad, or just make a wedge shim?

Also, the front suspension seams odd, with car at the correct ride height , the frame bottom almost 6 1/2" of the ground, the front control arms are significantly pointed at an upward angle, most all race suspension when weighted are about level.
Any one have pictures of theres to compare?
Thanks
